public static String createArrayTypeBindingKey(String typeKey,
int arrayDimension)
For example:
createArrayTypeBindingKey("Ljava/lang/Object;", 1) -> "[Ljava/lang/Object;"
createArrayTypeBindingKey("I", 2) -> "[[I"
typeKey - the binding key of the given typearrayDimension - the given array dimension
public static String createParameterizedTypeBindingKey(String genericTypeKey,
String[] argumentTypeKeys)
For example:
createParameterizedTypeBindingKey(
"Ljava/util/Map<TK;TV;>;",
new String[] {"Ljava/lang/String;", "Ljava/lang/Object;"}) ->
"Ljava/util/Map<Ljava/lang/String;Ljava/lang/Object;>;"
createParameterizedTypeBindingKey(
"Ljava/util/List<TE;>;", new String[] {}) ->
"Ljava/util/List<>;"
genericTypeKey - the binding key of the generic typeargumentTypeKeys - the possibly empty list of binding keys of argument types
public static String createTypeBindingKey(String typeName)
For example:
createTypeBindingKey("int") -> "I"
createTypeBindingKey("java.lang.String") -> "Ljava/lang/String;"
createTypeBindingKey("boolean[]") -> "[Z"
typeName - the possibly qualified type name
public static String createTypeVariableBindingKey(String typeVariableName,
String declaringKey)
For example:
createTypeVariableBindingKey("T", "Ljava/util/List<TE;>;") ->
"Ljava/util/List<TE;>;:TT;"
createTypeVariableBindingKey("SomeTypeVariable", "Lp/X;.foo()V") ->
"Lp/X;.foo()V:TSomeTypeVariable;"
typeVariableName - the name of the given type variabledeclaringKey - the binding key of the type or method the type variable belongs to
public static String createWilcardTypeBindingKey(String typeKey,
char kind)
Signature.C_STAR, Signature.C_SUPER, or Signature.C_EXTENDS.
If the wildcard is Signature.C_STAR, the given type binding key is ignored.
For example:
createWilcardTypeBindingKey(null, Signature.C_STAR) -> "*"
createWilcardTypeBindingKey("Ljava/util/List<TE;>;",
Signature.C_SUPER) -> "-Ljava/util/List<TE;>;"
createWilcardTypeBindingKey("Ljava/util/ArrayList;", Signature.C_EXTENDS) ->
"+Ljava/util/ArrayList;"
typeKey - the binding key of the given typekind - one of Signature.C_STAR, Signature.C_SUPER, or Signature.C_EXTENDS
createWildcardTypeBindingKey(String, char, String, int)
public static String createWildcardTypeBindingKey(String genericTypeKey,
char boundKind,
String boundTypeKey,
int rank)
Signature.C_STAR, Signature.C_SUPER, or Signature.C_EXTENDS
the given bound type binding key and the given rank. If the wildcard kind is Signature.C_STAR,
the given bound type binding key is ignored.
For example:
createWildcardTypeBindingKey("Ljava/util/ArrayList;", Signature.C_STAR, null, 0) -> "Ljava/util/ArrayList;{0}*"
createWildcardTypeBindingKey("Ljava/util/ArrayList;", Signature.C_SUPER, "Ljava/lang/String;", 0) -> "Ljava/util/ArrayList;{0}-Ljava/lang/String;"
createWildcardTypeBindingKey("Ljava/util/HashMap;", Signature.C_EXTENDS, "Ljava/lang/String;", 1) ->
"Ljava/util/HashMap;{1}+Ljava/lang/String;"
genericTypeKey - the binding key of the generic typeboundKind - one of Signature.C_STAR, Signature.C_SUPER, or Signature.C_EXTENDSboundTypeKey - the binding key of the bounding type.rank - the relative position of this wild card type in the parameterization of the generic type.
public BindingKey getDeclaringType()
null.
Note that only binding keys for references to methods and fields are fully supported. The binding keys for declarations will not have type parameters.
